The dimensions of the "body positive" dolls reflect a real, healthy body, something that has been lacking in doll culture for too long, members of the popular Kmart Mums Australia Facebook page claimed.

The mums were introduced to the wonders of the Anko Doll two months ago, when member Al Wilko posted to the group.

"Spotted these 'Glamour Dolls' today," Ms Wilko said.

"Same height as Barbie but twice the width, ie, a normal human size. How good!"

More than 3000 people have liked the post, with many parents vowing to pay a visit to the hugely popular department store to purchase one for their kids.

Some mums commented that they loved the dolls "simple, natural makeup look".

"Compared to Barbies, who have waist to hip and bust ratios that are completely abnormal and would not naturally possible on most humans, these dolls have more realistic figures," Caitlin Hancock wrote.

Aneeta Rani commented that the dolls "actually look like normal women, with thighs".

So why should you buy these alternatives to the original range of kids dolls?

Oh, let me count the ways …

'CURVY' BARBIES

While Mattel recently released a "curvy" version of their usual stick-thin offering, the doll barely resembles a size 10 in real life.

Not the smartest move, calling a size 10 girl "curvy", Mattel.

Regardless, the rest of the manufacturer's range, since its launch in 1959, largely portrays unrealistic images of what it means to be a woman.

Let's be honest: Barbie is a bimbo. She's mostly white and privileged, extremely thin, and forever on the hunt for a man.

Even when she's a rocket scientist or running for President, she's gotta tell the world about it and hopes her Ken is somewhere around the corner.

A pair of heels, a man and a white picket fence? That sounds swell!

Other totally backward reincarnations of Barbie included Teen Talk Barbie who could say things like "Math class is tough!" as well as Slumber Party Barbie, who came equipped with scales and a book called How to Lose Weight. One of the rules of the book is "Don't Eat!"

A study, published in the Body Image journal, examined all brands of dolls sold across the US and found that 62 per cent of female dolls "had a noticeably thin body".

The report concluded that thin dolls were portrayed with "more sex object features" than larger dolls.

"These include revealing, tight clothing and high-heeled shoes, body positioned with a curved spine, bent knee and head cant," the report said.
